The Theater and Professional Series four π loudspeakers are an easy load, both in terms of impedance and efficiency. The Stage four π has the efficiency, but the impedance fluxuates a little more. However, if you add the midhorn, it tends to smooth the impedance curve. It also provides directivity and smoother midrange.
